Healthy Rabbit Diet and Hay: A Practical Daily Guide

The foundation of an adult rabbit’s diet is clean, dry grass hay. Hay supplies the long-strand fibre needed for normal gut movement and supports natural tooth wear. A rabbit should be able to reach fresh hay throughout the day and night. Replace wet, dusty, mouldy or strongly musty hay immediately.

Good grass-hay examples include timothy, orchard and meadow hay. Locally produced grass hay may also be useful when it has been correctly identified, dried and stored. Fresh, pesticide-free grass can contribute fibre, but introduce it gradually and never use lawn-mower clippings because they heat and ferment quickly. Alfalfa is richer in protein and calcium and is usually more appropriate for growing rabbits, pregnant or nursing does, or individual rabbits whose veterinarian recommends it.

Provide clean drinking water at all times. A heavy bowl often encourages natural drinking and is easy to inspect, although a properly working bottle may also be used. Wash containers daily and check that outdoor water has not become hot.

Offer a varied selection of rabbit-safe leafy greens in sensible portions. Introduce one unfamiliar food at a time over several days so changes in appetite, stool or comfort are easier to identify. Pellets should be fresh, plain and measured rather than used as the main food. Avoid colourful mixes containing seeds, corn pieces, nuts or sugary dried fruit.

Fruit and starchy vegetables are treats, not daily staples. Sudden diet changes can upset digestion. When changing hay, greens or pellets, make the transition gradually unless a rabbit-experienced veterinarian gives different instructions.

Daily check
• Unlimited clean grass hay is available.
• Fresh water is available and the container works.
• The rabbit is eating willingly and producing normal droppings.
• Greens are clean and newly introduced foods are limited.
• Pellets and treats are measured.

Seek urgent veterinary help when a rabbit stops eating, produces fewer or no droppings, appears bloated, sits hunched, becomes unusually quiet or shows signs of pain. Rabbits can deteriorate quickly, and home feeding advice is not a substitute for diagnosis.

Build the routine around forage and water
For most healthy adult rabbits, suitable grass hay or forage is the everyday foundation and should remain clean, dry and readily available. Provide fresh water and confirm bowls or bottle valves work. Discard damp, mouldy, dusty or contaminated hay rather than mixing it into fresh feed.
Keep other foods measured and consistent
Choose pellets and leafy foods appropriate for the rabbit’s age and health, and follow reputable rabbit-care guidance or a veterinarian’s plan for amounts. Introduce a new leafy food gradually, one item at a time. Treats should remain small and occasional; do not let them displace hay. A sudden change in appetite or droppings deserves prompt veterinary attention.
Use a simple daily check
At the same routine check, note hay availability, water access, what portion was offered, leftovers and droppings. Compare with that rabbit’s normal pattern instead of relying on a universal portion that ignores age, body condition or health. Ask a rabbit-experienced veterinarian for a tailored plan for growing, pregnant, nursing, overweight, underweight or unwell rabbits.
